1. an object has a mass of 10g and a volume of 50ml. what is the density?
explain and show your work

2. an object has a density of 2 g/ml and a mass of 20g. what is the volume?
explain and show your work.

15 points

1. 0.2 g/mL

The relationship between mass, density and volume of an object is

where

d is the density

m is the mass

V is the volume

For the object in this problem, we have

m = 10 g

V = 50 mL

Substituting into the equation,

2. 10 mL

In this exercise we know:

- The density of the object: d = 2 g/mL

- The mass of the object: m = 20 g

Therefore, we can re-arrange the previous equation to find the volume:

And substituting values into the equation, we find

an electric circuit

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
